How to propagate yellow rose

The propagation of Rosa lutea by division

Rosa rugosa has strong tillering ability, grows quickly, and does not bear fruit after flowering, so it is often propagated by division, which is simple, quick, and has a high survival rate.

When Rosa rugosa is propagated by division, it is usually done in early spring in March when the plant begins to revive and sprout again. When dividing the yellow rose, the branches should be pruned first, and then the entire plant should be dug up with its roots. Use a knife to split the yellow rose from the root and divide it into several parts. Each part should have at least 1 to 2 branches and part of the root system. Plant the divided yellow rose plants separately. Water them once after planting, and then strengthen fertilizer and water management.

Cutting propagation of Rosa lutea

Yellow rose is mostly propagated by cuttings in spring. The temperature is low in spring, so softwood cuttings are mostly used. In June and July, semi-lignified branches of the current year are selected for cuttings.

Select strong woody branches of the current year, cut 10-15cm long branches for cuttings, leave 2-3 leaves, and insert them into the sand bed.

Keep the soil moist after cuttings of Rosehip thorns. It will generally take root in about 40 to 50 days. Transplant again in the spring of the second year.

Grafting propagation of Rosa serrata

Grafting propagation is usually carried out from December to early January of the following year.

When propagating Rosa jasminoides by grafting, the wild Rosa jasminoides that are easy to root should be used as the rootstock, and the branches and buds grown in the current year of Rosa jasminoides should be used as the scion. It is best to cut the grafted branches as they are used, and remove all the leaves after cutting. After removing the yellow rose buds, tie them tightly with plastic film and pay attention to the moisture of the yellow rose buds. Observe the growth status of Rosa rugosa 10 days after grafting.

Grafting propagation is simple and easy with a high survival rate and many flowers. The advantage of grafting is that it facilitates shaping and pruning.

Layering propagation of Rosa lutea

Grafting propagation of Rosa rugosa is usually carried out in July. Press the young branches of Rosa rugosa into the soil, wait for them to take root, and then separate them from the mother plant and transplant them in the spring of the following year.
